TOPIC: PH for regular average bonsai soil

There seems to be a consensus when people talk about soil and ph; "lightly acidic" for most bonsai, "acidic" for azaleas.
So my question is, how much is lightly acidic? 6.5? 5.0? 3.0?
Yes, I've got this ph soil probe, but no clue about the numbers I am aiming for...

Auk, in my experience, the recommended substrate varies wildly, depending on the seller and on the type of tree, I guess.
Some people say "Akadama"! Others show a wide range of mixes, almost all agree on inorganic, all vow to good drainage.
You see, I have been buying "bonsai soil" from various sources to test, and they are never the same.
Thanks for your answers, I won't fret about PH so much anymore!
